Hot Topic Solar System Earth Climate
 
Extreme Weather Preceded Collapse of Maya Civilization
Topic: Climate
11/11/12
A new study shows that extreme weather decimated the political culture and population of the ancient Maya.

Climate Likely to be on the Hotter Side of Projections
Topic: Climate
11/10/12
A new NASA-funded study finds climate model projections that show a greater rise in global temperature are likely to prove more accurate than those showing a lesser rise. The study helps narrow the range of global warming expected in the coming decades and beyond.

Global Warming and The Great Dying
Topic: Climate
11/06/12
A new study shows that global warming was responsible for the slow recovery of plants and animals following the largest known mass extinction in Earth's history. The study could have implications in understanding how climate change could affect the future on life on our planet.

Closing the Ozone Hole
Topic: Climate
09/19/12
In this interview, NASA atmospheric scientist Pawan Bhartia discusses what it was like to play a role an 'unparalleled environmental success story' - the discovery and stabilization of Earth's ozone hole.

The Contrasting Consequences of a Warmer Earth
Topic: Climate
09/05/12
A new study based on studies of the geological and fossil record of Earth suggests that biodiversity generally increases as our planet warms.

Climate Mystery of the Deep
Topic: Climate
08/12/12
By studying ancient ice volume and deep-ocean temperatures, scientists have made a major breakthrough in understanding the Earth's climate.

Earth Absorbs Carbon Pollution
Topic: Climate
08/06/12
Despite sharp increases in carbon dioxide emissions by humans in recent decades that are warming the planet, Earth's vegetation and oceans continue to soak up about half.

Sea Chemistry and Climate Change
Topic: Climate
07/23/12
A new study on ocean chemistry is shedding light on one potential cause of a cooling trend experienced on Earth in the past 45 million years.

Toxic Cyanobacteria and Global Warming
Topic: Climate
07/08/12
New research indicates that global warming may be leading to an increase in the amount of toxins produced by populations of cyanobacteria.

Ice Cores May Not Be Accurate Thermometers
Topic: Climate
06/27/12
Ice samples pulled from deep inside glaciers have long served as historical thermometers. However, a new study questions whether or not oxygen isotopes ratios in the ice cores can be interpreted as a signal of temperature.
